OIIi-GAS-MAKING APPARATUS.

Application filed May 31,

To all whom it may cozzcem.'.

. Be it known that I, WILLIAM E. L.- CAL- :viN, a citizen ofthe United States, and

. 'residentof the city and county of San Francisco, State of California, have inventednew and useful Improvementsin Oil-Gas- Making Apparatus, of which the following is a specification. i r I My invention has for its object-apparatus for efficiently, quickly and continuously producing gas from fuel oil.

By referring to the accompanying drawing my invention will be made clear,

Fig. 1 is a vertical cross section through apparatus embodying my invention.

Fig. 2 is a plan view of reduced scale of the-apparatus of Fig. 1 for the purpose of or heating chambers 1 and 2 and a pair ot lower or making chambers 3 and. 4, respectively. A partition floor is shown at 5 and 6 which has a large number of openings therethrough and thereabove is the checker brick work 7 8, 9, 10, and which is built up with'numerous spaces or interstices therebetween whereby vapors may pass freely through the said brick from the upper chambers to the lower chambers. A connecting passageway for making and fixing the oil gas is shown between the lower portions of the two chambers at 11, and at 9, 10, 12, are shown other built-up portions of checker brick work, the purpose of which will be more fully described below. At 13; is a passage connectingthe lower chambers 3, 4, from which a common gas off-take con nection 14-discharges to the conventional wash box or scrubber. At 15, 16, are passages having air inlets at 17, 18, under the control of valves 19, 20, respectively, and at '21, 22, are conventional stack valves pref erably of the trap form. A steam pipe is shown at 23 supplying a network of pipes, valves, and nozzles, more particularly-described below, and an oil supply pipe M24 1923. serial N6. 642,455.

also supplies a network of distributing pipe outlets and valves as 31, 32.

An air supply pipe 26 which may be connected with a master air supply pipe 25, supplies the valves and bifurcated nozzles 28, 28 with air through connecting pipe 27, valve and bifurcated nozzle connections 29, 29 are supplied with steam through connections 80, 81, from the master steam supply as 3 These nozzles are primarily controlling the temperature and :for cleaning purposes and may be arranged in any position desired, but should be directed so as to'cre ate a velocitythrough the connecting passage 11.

At 31 is shown a pipe externally encircling the chamber 3 fed from the oil supply pipes 24, 30, whereby oil may be introduced as desired'into the upper portion 'of the lower chamber 3 and around the periphery thereof. A similar oildistributing ring pipe is shown at 32 for'the upper chamber and at and 34 are shown steam pipes preferably also encircling the said chamber for the purpose of supplying steam to the oil supply nozzles in the conventional way.

The operation is as follows:

It is to be understood that each of the pairs of chambers are substantial duplicates and eachis equipped with the oil, air and steam pipes and nozzles to effect the heating of the chambers as specifically described for one of said chambers above and the making of gas. Various arrangements of piping and valves and accessory devices may be employed other than those shown and within the spirit of my invention and I desire to be understood asclaiming all such.

The trap valve2l being closed and22 being open an air blast is turned through the pipe 17 and passage 15 into the chamber 1. The spray nozzles as 40, 41, are lighted and the flame blown down against, and heats the bricks at 7 9, 12, 10, and to a less degree the bricks at 6, and 8. When these have been heated to the desired degree the spray nozzles are closed off, the trap valve 22 and valve 19 closed whereby no air is admitted I 1, and also from the nozzles 70:

freely through the duct 14 from chambers 3 and 4. The quantity of the oil and steam is regulated by the operator depending upon the area of the heated brick and the heat intensity thereof, with which the oil from the spray nozzles comes in contact. This gas making step exhausts the'heat of the bricks and when they have become chilled to a de gree which Wlll not efiiciently produce. further gas, the trap valve 21 and valve 20 is opened and air is then blown through the chamber 2, and the nozzle sprays 60, 61, lighted and the bricks 8, 10,12 and 9, and to a less degree 7, are in the order .named heated from the said sprays, after which trapvalve. 21 and the valveQO are closed and the oil and steam are fed into the chamber 3'and 4 in the same manner as formerly described. It will thus beseen that a erfect heat interchange is attained between the two VQSSfBlS and a most ellicient and steady operation is secured.-

, The processdescribed therefore results in, first, the heating of the two chambers in series from left to right, followed by the making of gas which flows in the same direction, namely: from left to right, after which through themanipulation of the valves as described above the chambers are again heated in the opposite direction, namely:

from right to left, after which comes the gas making step from right to left, which completes the cycle; the process being thereafter repeated continuously.

I claim:

1. In a gas makingapparatus, a plurality of vertical vessels each having a grill partition dividin the vessel into upper and lower chambers, t e saidvlower chambers crossconnected by a gas making and fixing passage having a gas outlet, checker brick in said chambers and in said passage, a valve controlled air inlet to and a valved outlet from the top of each upper chamber and sage having a gas outlet. checker brick in said chambers and in said passage, a valve controlled air inlet to and a valved outlet from the top of each upper chamber and steam and oil spray nozzles in each of the upper and each of the lower chambers, and. steam and air inlet connections. to the lower part upper and each of the lower chambers, said .nozzles spaced about the peripheryof the chambers and each of said nozzles valve controlled.

et. In gas making apparatus, a plurality of vertical vesselseach having a grill partition dividing the vessel into upper and lower chambers, the said lower chambers crossconnected by a gas making and fixing pas-- sage having a gas outlet, checkerbrick in said chambers and in said passage, a-valve controlled air inlet to and a valved outlet from the top of each upper chamber and steam and oil spray nozzles in each of the upper and each' of the lower chambers, and steam and air inlet connections to the l owerpart of 5. In, gas making apparatus, a plurality of vertical vessels each having a grill partition dividing the vessel into upperand lower chambers, the said lower chambers crossconnected by a gas making and fixing passagehaving a gas outlet, checker brick in said chambers and in said passage, a valve controlled air inlet to and a valved outlet from the top of each upper chamber and steam and oil spray nozzles in each of the upper and each of the lower chambers, said nozzles spaced about the'periphery of the chambers and each of said nozzles valve con trolled, and valved stem inlet nozzles ani valved air. inlet nozzles disposed in the lower part of each lower chamber and directed toward said making and fixing passage.
